Description

The present invention relates to a cooking device equipped with a cooking plate suitable for Hiroshima-style okonomiyaki.

  Traditionally, a teppanyaki shop where the cook and the customer face each other and the cook cooks on the cooking plate in a form facing the cooking plate installed in the central opening of the table. Is known (see Patent Document 1).

  The cooking device installed in this type of store is a face-to-face system with a cooking table in between, so both the customer on the back side of the table and the chef on the near side can receive heat from the heat source under the cooking plate. A heat shield means for blocking the exhaust heat is installed (see Patent Documents 2 and 3), or exhaust heat gas generated near the lower surface of the cooking plate is forced through the outside of the heat source from directly below the peripheral edge of the cooking plate. A technique for discharging is required (see Patent Document 4).

  By the way, it is generally said that a thicker cooking plate such as an iron plate emits a larger amount of far-infrared rays, and cooked items such as okonomiyaki and steak are baked deliciously. In that case, it is said that the central portion of the cooking plate is about 280 degrees and that the peripheral portion is preferably about 200 degrees.

  In such a cooking plate, because cooking at the center is high temperature cooking, it is necessary to raise the thickness of the thick cooking plate to a temperature at which cooking can be performed in a short time, and a high calorie heat source is required. It was.

  However, as shown in Patent Document 4, when a forced exhaust system such as an exhaust duct device is attached to the heating cooker, the heat source calorie is quickly taken away by the forced exhaust system, and the calorie from the heat source is lost. It could not be used effectively, and the result was contrary to the recent demand for energy-saving cooking devices.

  In view of the above, an object of the present invention is to provide a cooking plate that can efficiently form a high-heat cooking region with less calories and a cooking device equipped with the cooking plate.

In order to achieve the above object, the present invention provides a plurality of heat sources arranged at intervals inside the cooker body, and a heating cooking plate disposed at an upper opening of the cooker body at a distance from the heat sources. The cooking plate is formed in a flat plate shape with a cooking surface disposed above the heat source, and the cooking surface has a plurality of cooking regions for high heat and low heat therebetween. The surface is divided into cooking regions, the back side of the cooking plate is formed in an uneven shape corresponding to the plurality of heat sources, and the thickness of the concave portion is made thinner than the other portions, and the surface corresponding to the uneven portion The cooking surface on the side is the cooking region for high heat, and the cooking surface on the front side corresponding to the flat portion between the plurality of uneven portions formed on the back surface side of the cooking plate is the cooking region for low heat. characterized in that was.

  According to the said structure, when the part of the back surface side corresponding to a heat source is formed in unevenness, the surface area is set larger than a flat part, and it becomes easy to receive the radiant heat from a heat source. Moreover, since the thickness of the recessed part of an uneven | corrugated | grooved part will be formed thinner than another part, a cross-sectional area will become smaller than another part, and it will be heated up to high temperature with a little calorie | corresponding part. Therefore, a high heat cooking area can be efficiently formed with a small number of calories.

  Concave and convex shapes include, for example, a mode in which a plurality of grooves are arranged in parallel, a mode in which a plurality of grooves are arranged in a grid pattern in the vertical direction and the horizontal direction perpendicular thereto, and the concave portions formed by small depressions are scattered or staggered It is conceivable to arrange in a manner. Examples of the groove cross-sectional shape include a triangle, a rectangle, and a trapezoid. The recess made of a small depression can be exemplified by a circle, an ellipse, a polygon, and the like in plan view. In this case, the vertical cross-sectional shape of the recess can be exemplified by a triangle, a square, or the like. In short, the shape of the recess may be set to have a surface area that matches the calories in the cooking region for high heat.

  Further, the region of the concavo-convex portion can be set to various shapes such as a rectangle, a circle, and an ellipse. What is necessary is just to select this suitably according to cooking object.

  Since the cooking region for high heat becomes hotter than the cooking region around it, a temperature difference can be provided between the cooking region around the cooking region for high heat. For example, when used in a heating cooker having a plurality of heat sources, the cooking plate has a plurality of concave and convex portions corresponding to the plurality of heat sources, and a plurality of the concave and convex portions are formed at intervals on the back side, and the surface corresponding to the concave and convex portions. The cooking surface on the side can be used as a cooking region for high heat, and the cooking surface on the surface side corresponding to the area between adjacent uneven portions can be used as a cooking region for low heat.

  According to the above configuration, a high heat cooking region and a low heat cooking region can be formed. For example, noodles such as fried noodles are cooked in the high heat cooking region, and okonomiyaki dough and ingredients are cooked in the low heat cooking region. Both can be cooked at the same time on the same cooking plate, and okonomiyaki can be cooked efficiently by superimposing the finished dishes. Similar to cooking of okonomiyaki, cooking in teppanyaki can be performed using a high heat cooking area and a low heat cooking area.

  Furthermore, in this invention, the surrounding wall for interrupting | blocking the heat which escapes from the heat source to the circumference | surroundings can be provided around the uneven | corrugated | grooved part. Thereby, since the heat radiated from the heat source to the concavo-convex portion can be temporarily stored in the concavo-convex portion and the thermal calorie can be used effectively, the heat source having a low calorie can be used, and further energy saving can be achieved.

  In particular, when the cooking device adopts a forced exhaust system, an air flow from the heat source to the suction port of the intake duct is generated, and the heat radiated from the heat source to the uneven part is easy to escape. Since the heat radiated from the heat source to the concavo-convex portion is temporarily stored in the concavo-convex portion and consumed by the concavo-convex portion, efficient heat utilization is possible.

  In this case, it is possible to adopt a configuration in which the enclosure wall is provided on one side of the intake port side and two sides adjacent to the intake port that forcibly sucks heat from the heat source. Of course, one side of the air intake side is shielded by the surrounding walls on both sides, so that the air flow drawn to the air intake port bypasses the left and right side walls from the heat source and is sucked to the air intake side. The heat storage in the concavo-convex portion proceeds and the heat can be used effectively.

  Here, the reason why the enclosure wall is three-sided is that there is little significance in providing the enclosure wall because the remaining surface is on the side opposite to the intake port. Of course, it is of course possible to adopt a configuration in which the surrounding wall is provided on the four surfaces around the concavo-convex portion.

  Further, an opening can be formed in the enclosure wall so that the exhaust from the heat source, in particular, the combustion gas burner can be forcibly exhausted. Here, the aperture ratio of the openings may be the same for all three surfaces, but the aperture ratio of the openings formed on one surface of the intake port on the enclosure wall is the aperture ratio of the openings formed on the two adjacent surfaces. You may employ | adopt the structure set smaller than this.

  According to the above configuration, the flow rate balance between the air flow directly toward the intake port and the air flow that bypasses the side wall opening and flows toward the intake port by lowering the opening rate on the intake port side than the opening rate of the side walls on both sides. Can take.

  Moreover, in this invention, the several heat source can be arranged in the inside of a cooking appliance main body at intervals, and the heating cooker which has arrange | positioned the said heating cooking board to the upper side opening can be provided. Thereby, a high-heat cooking area | region can be formed efficiently with the calories of few heat sources.

  In this case, the heat source can be adopted regardless of electricity or gas, but is particularly effective as an energy saving measure in a cooking device using a gas burner or a carbon lamp heater as a heat source.

  As described above, according to the present invention, a part of the back surface side corresponding to the heat source is formed in an uneven shape, so that the surface area thereof is set larger than that of the flat portion, and it is easy to receive radiant heat from the heat source. Moreover, since the thickness of the concave portion of the concave and convex portion is formed thinner than the other portion, the cross-sectional area becomes smaller than the other portion, and accordingly, the temperature can be raised to a high temperature with less calories. An energy-saving cooking device can be provided.

It is a disassembled perspective view of the principal part of the heating cooker which is embodiment of this invention. It is a top view of a heating cooker. It is a front view of a heating cooker. It is a side view of a heating cooker. It is an expanded sectional view of an uneven part. (A) (b) is an expanded sectional view which shows the other example of an uneven | corrugated | grooved part, respectively.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing a cooking plate showing a main part of the present invention and a gas burner as a heat source. 2 to 4 show a cooking device with an exhaust duct device.

The cooking device 1 of the present embodiment includes a cooking table 2, gas burners 3 and 4 that are heat sources, a heating cooking plate 5 such as an iron plate placed on top of the cooking table 2, and heat radiated from the heat source. And an exhaust duct device 6 for intake and exhaust to the outside.
The cooking table 2 includes a top plate portion 7, four legs 8 that support the four corners thereof, and two-stage shelves 9 and 10 provided below the top plate portion 7 and between the legs 8. Yes.

  The center of the top plate portion 7 is opened, and the cooking plate 5 is placed in the opening. Between the top plate 7 and the upper shelf 9, gas burners 3 and 4 serving as heat sources are arranged at intervals in the left-right direction. The gas burners 3 and 4 are ring burners and are connected to the gas front pipe 11 arranged in the left-right direction on the front side of the cooking table 2 so that the gas cock 13 supplies and stops the gas to the gas burners 3 and 4. It has become.

  On the front side of the top plate portion 7, a residue receiving rod 14 for receiving the residue generated on the cooking plate 5 is provided, and a drop hole 14 a for dropping the residue is formed in the central portion of the residue receiving portion 14. A recovery box 15 for recovering waste is provided below the upper shelf of the cooking table 2 below.

  The cook is positioned on the front side where the collection box 15 is arranged, and the customer can sit on the back side of the cooking table 2 and enjoy cooking and eating in a face-to-face manner. Although not shown, a counter table for a meal space may be attached to the top plate portion 7 on the back side.

  The exhaust duct device 6 is connected to an exhaust heat intake tower 16 having an upward exhaust heat intake port on the back side of the upper shelf 9 of the cooking table 2, and a lower end of the exhaust heat intake tower 16 via an air volume adjusting damper 17. The exhaust duct 18 disposed on the lower shelf 10 of the main body, the exhaust heat fan 19 connected to one side in the left-right direction of the exhaust duct, and the side portion of the cooking table 2 to accommodate the exhaust heat fan 19 And the exhaust tower 22 connected to the exhaust side of the exhaust heat fan 19, and the air volume adjustment damper 17 adjusts the air volume, thereby adjusting the suction air volume from the exhaust heat intake tower 16. It can be done.

  The cooking surface 5 is formed in a flat plate shape with a cooking surface disposed above the heat source. In the cooking plate 5, a part on the back side corresponding to the heat source is formed in an uneven shape, and an uneven portion 25 is formed. The thickness of the concave portion of the concavo-convex portion 25 is formed thinner than other portions.

  For example, when the thickness of the cooking plate 5 is about 20 mm, a recess 25a having a depth of about 5 to 12 mm is formed (however, the depth of the recess 25a is not limited to the above setting range). The pitch of the grooves (recesses 25a) can be set at a pitch of 10 mm to 20 mm.

  Thereby, the surface area of the uneven | corrugated | grooved part 25 is set so that it may become larger than the other flat part 27, and it is easy to receive the radiant heat from a heat source. Therefore, the cooking surface on the front surface side corresponding to the concavo-convex portion 25 on the back surface is a cooking region for high heat 5A compared to the surrounding cooking region 5B. The high heat cooking area 5A can be set to a temperature of about 260 to 300 degrees, for example.

  Moreover, the magnitude | size of the uneven | corrugated | grooved part 25, ie, the magnitude | size of the cooking area 5A for high heat | fever, can be variously set with the to-be-cooked material to cook. For example, it can be set to a size of about 400 mm to 600 mm × 400 mm to 600 mm.

  As shown in FIG. 1 and FIG. 5, the uneven shape of the uneven portion 25 can include an embodiment in which a plurality of grooves (recess portions 25 a) are arranged in parallel. The length direction of the groove can be set in the front-rear direction from the near side to the far side, and the heat generated from the heat source can be set easily toward the exhaust heat intake port.

  In addition to the above, the concavo-convex shape is an aspect in which a plurality of grooves (concave portions 25a) are arranged in a grid pattern in the vertical direction and in the lateral direction perpendicular thereto, or an aspect in which the concave portions made up of small depressions are arranged in a dotted or staggered manner It may be adopted.

  Further, in the example of FIG. 5, the groove cross-sectional shape of the recess 25a is formed in a triangular shape, but it is needless to say that other shapes may be used. For example, the groove cross-sectional shape can include a triangle, a rectangle (see FIG. 6A), a trapezoid, and a semicircle (see FIG. 6B).

  Further, the concave portion 25a formed of a small depression may be any of a circle, an ellipse, a polygon, and the like in plan view. In this case, the vertical cross-sectional shape of the recess can be exemplified by a triangle, a square, or the like. In short, the shape of the recess may be set so as to have a surface area that matches the calories in the cooking region for high heat 5A.

  Moreover, the cooking region 5A for high heat of the uneven | corrugated | grooved part 25 can be variously set according to cooking object, such as circular and an ellipse other than the rectangle shown in FIG.

  As shown in FIG. 2, a low heat cooking region 5 </ b> B is formed between the high heat cooking regions 5 </ b> A on the cooking surface on the surface side corresponding to the flat portion 27 between the two adjacent uneven portions 25. Is done. This low heat cooking region 5B can be set to a temperature of about 160 to 200 degrees, for example.

  Note that the cooking region 5A for high heat and the cooking region 5B for low heat can be distinguished from the cook side by looking at the operation portion of the gas burner and the red hot state when viewed from the front side. However, it is also possible to distinguish between the two regions by directly marking the cooking plate or by marking the top plate.

  In addition, the uneven | corrugated | grooved part 25 can form the back surface of the heat cooking board 5 by a milling process.

  Further, an enclosing wall 28 is provided around the concavo-convex portion 25 so as to surround the outer periphery of the heating area for high heat of the cooking plate 5 so as to block and store heat that escapes from the heat source.

  This enclosure wall 28 is provided on three sides of the side wall 28a on the inlet side and the two side walls 28b and 28c adjacent to the side wall 28a toward the exhaust heat intake port that forcibly sucks heat from the heat sources 3 and 4. It has been. Since the remaining surface is on the side opposite to the air inlet, it is open because there is little significance in providing the enclosure wall 28.

  The enclosure wall 28 is welded and fixed to the back surface of the cooking plate 5 (screw fixing may be used). However, the enclosure wall 28 may be attached to the cooking table 2 instead of being fixed to the cooking plate 5. The height of the surrounding wall 28 is set at a position slightly higher than the upper surfaces of the gas burners 3 and 4 that are heat sources, so that the gas burners 3 and 4 can be burned smoothly. The height of the surrounding wall 28 is set to about 60 mm to 80 mm, for example.

  Further, openings 29a and 29b are formed in the enclosure wall 28 so that exhaust from the heat source, in particular, the gas burners 3 and 4 is forcibly exhausted. The opening ratios of the openings 29a and 29b are set such that the opening ratio of the side wall 28a on the intake port side is smaller than the opening ratios of the side walls 28b and 28c on both sides thereof. This lowers the opening ratio on the inlet side from the opening ratio on the side walls on both sides, thereby balancing the flow rate of the air flow directly toward the intake port and the air flow that bypasses the side wall opening and flows toward the intake port. For rectification. Specifically, the openings on the side wall 28a on the intake port side have a plurality of small circular holes arranged in the lateral direction, and the openings on the side walls 28b and 28c on both sides thereof are rectangular openings larger than the small circular holes. 29b is formed.

  When cooking the food to be cooked on the heating cooking plate 5 using the heating cooker 1 having the above configuration, the gas burners 3 and 4 as heat sources are ignited and the exhaust heat fan of the exhaust duct device 6 is driven. Then, the exhaust heat gas burned in the gas burners 3 and 4 is sucked into the exhaust heat fan 19 and sucked from the exhaust heat intake tower 16 located on the back side of the cooking table 2, and passes through the exhaust duct 18 to the exhaust tower 22. To the outside.

  Due to the forced suction of the exhaust duct device 18, exhaust heat from the gas burners 3 and 4 is directly exhausted to the intake port on the back side of the cooking plate 5, and the efficiency of heating the back side of the cooking plate 5 may deteriorate. There is.

  However, in this example, since a part on the back side corresponding to the heat sources 3 and 4 is formed in an uneven shape to form the uneven part 25, the surface area is larger than that of the flat part 27 of the low heat cooking region 5B. It is set large, and it is easy to receive radiant heat from the heat source. And since the thickness of the recessed part 25a of the uneven | corrugated | grooved part 25 will be formed thinner than another part, a cross-sectional area will become smaller than another part, and the part 5A of cooking areas for high heat | fever with a little thermal calorie by that much Can be heated to a high temperature.

  Also, the high heat cooking area 5A is hotter than the adjacent low heat cooking area 5B. For example, in the low heat cooking area 5B, okonomiyaki dough and ingredients such as meat and vegetables are cooked, and in the high heat cooking area 5A. Okonomiyaki can be efficiently finished by cooking noodles such as fried noodles, cooking them on the same cooking plate 5 in the middle, and overlaying the finished products.

  Further, since the surrounding wall 28 is provided around the concavo-convex portion 25 to block the heat escaping from the heat sources 3 and 4, the heat radiated from the heat sources 3 and 4 to the concavo-convex portion 25 is temporarily stored here. , Heat calories can be used effectively. Therefore, a heat source having a low calorie can be used, and further energy saving is possible. For example, the same effect was obtained with a heat source of 4000 to 4500 kcal / h that required a heat source of 7000 kcal / h.

  In particular, when the heating cooker 1 adopts a forced exhaust system, an air flow from the heat source to the suction port of the intake tower is generated, and the heat radiated from the heat source to the concavo-convex portion 25 is easily escaped, The heat radiated from the heat source to the concavo-convex portion 25 by the enclosure wall 28 is temporarily stored in the concavo-convex portion 25 and consumed here, so that efficient heat utilization is possible.

  In this case, openings 29a and 29b are formed in the enclosure wall 28 so that the exhaust from the heat source, particularly the combustion gas burner, is forcibly exhausted. It can be released efficiently. At this time, by reducing the opening ratio of the side wall 28a on the intake port side from the opening ratio of the side walls 28b and 28c on both sides, the air flow directly toward the intake port and the air that bypasses the opening of the side wall and flows toward the intake port The flow can be balanced with the flow and rectified, which is effective for energy saving measures.

  In addition, this invention is not limited to the said embodiment, Of course, many correction changes can be added within the scope of the present invention. For example, in the above example, a ring-shaped gas burner is illustrated as a heat source. However, the present invention is not limited to this, and an H-type gas burner may be used. Further, a heat source using electricity such as a carbon lamp heater, a halogen lamp heater, or a sheathed heater may be employed. In this case, since there is no need to release exhaust heat at the enclosure wall, it is not necessary to form an opening in the enclosure wall. Moreover, although the double burner was illustrated in the said example, it is good also as a counter-type heating cooker by arranging more burners than it. Furthermore, although the iron plate was mentioned as a cooking plate in the said example, this invention is applicable also to a stone plate.
